摘　　要：针对永磁同步电机(PMSM)易受外界扰动和参数不确定性的影响,此处设计了一种改进超螺旋滑模控制策略。该方法采用一种准滑动模态中的连续函数来替代符号函数,以克服传统滑模控制存在的抖振问题,并将比例控制和积分控制引入超螺旋滑模控制来提高控制系统对负载和参数变化的鲁棒性,采用Lyapunov函数对控制系统进行稳定性分析。实验结果表明,所设计的改进滑模控制器能有效抑制控制系统的抖振,实现控制系统的快速跟随和无超调工作,增强了系统的鲁棒性。An improved super-twisting sliding-mode control strategy is designed to address the susceptibility of permanent magnet synchronous motors(PMSM)to external disturbances and parameter uncertainties.This method uses a continuous function in a quasi-sliding mode to replace the sign function,in order to overcome the chattering problem of traditional sliding-mode control.Proportional control and integral control are introduced into the super-twisting sliding-mode control to improve the robustness of the control system to load and parameter changes.Lyapunov function is used to analyze the stability of the control system.The experimental results show that the designed improved slidingmode controller can effectively suppress the chattering of the control system,achieve fast tracking and non-overshoot operation of the control system,and enhance the robustness of the system.
